Language, Speech, and Hearing Services in Schools, 1996
Classroom acoustics are generally overlooked in American education. Noise, echoes, reverberation, and room modes typically interfere with the ability of listeners to understand speech. The effect of all of these acoustical parameters on teaching and learning in school needs to be researched more fully.

Classroom acoustics II: Acoustical conditions in elementary school classrooms
The Journal of the Acoustical Society of America, 1998Acoustical measurements of speech transmission index, reverberation time, early reverberation time, early-to-late energy ratios, loudness (or relative strength), articulation index, background noise levels, and signal-to-noise ratios were made in a number of elementary school classrooms in one school district to see how many rooms actually had ...

A green pathway to classroom acoustics: A comparison of classroom acoustic standards.
The Journal of the Acoustical Society of America, 2008Towne seems to have started the modern classroom acoustics movement, and Nixon was one of its earliest volunteers. Nixon contributed to an important success of that movement, the development of ANSI standard for classroom acoustics, S12.60-2002. Some of Nixon’s collaborations with Towne are remembered.

Classroom acoustics III: Acoustical model studies of elementary school classrooms
The Journal of the Acoustical Society of America, 1998A 1:4 scale model was constructed with a series of interchangeable wall and ceiling panels to allow a battery of acoustical tests to be conducted for a variety of classroom designs. The walls and ceiling of the room could be changed from sound absorbent to sound reflective materials quickly. Scale furniture was also constructed for the room.

A primer on classroom acoustics.
The Journal of the Acoustical Society of America, 2010Research involving quantitative and qualitative evaluation of classroom activities has shown that speech perception and intelligibility in elementary, middle, and high schools can be measured, modeled, and simulated based on an impulse response-based theory. The theory combines the vocal production of the speaker, the hearing abilities of the listeners,

Classroom demonstrations of acoustic beamforming
The Journal of the Acoustical Society of America, 2012A tabletop apparatus permitting demonstrations and hands-on student exercises in the acoustic beamforming of linear arrays is described. The apparatus can be used to demonstrate how interference effects from two or more linearly arranged sources produce patterns of maxima and minima as described by theory. A transmitting array is attached to the top of

Acoustic Conditions for Speech Communication in Classrooms
Scandinavian Audiology, 1991The purpose of this study was to measure reverberation times, background noise levels and Rapid Speech Transmission Index (RASTI) values in occupied and in unoccupied classrooms. Probability distributions of sound levels were also measured during classroom instruction.

The Journal of the Acoustical Society of America, 1998
This pilot study used participatory fieldwork in a number of kindergarten through eighth grade classrooms to evaluate the acoustic setting that supports learning. Dynamic interactions among administrators, teachers, students, parents, and research team members makes a difference in learning. It was found that classroom interaction depends on the social
